Adjustable strut rod

Wanna instal my new qa1 adjustable strut rod this week end
And would like to know your idea on what i plan to do

Like some people told me im suppose to remove
the lower control arm
To be able to remove the strut rod but what i wanna do
Is cut the old one in half so dont need to pull back the
control arm to release the strut rod

And i think i can instal the adjustable one if they are apart

Am I crazy or can it be don like I think
